Patent JP-H11145566-A (JP)
Title: Manufacture of 3-nitride semiconductor laser diode
Inventor: KOIKE MASAYOSHI
IPC: H01S5/323
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To improve light deflectivity at an end surface by improving flatness at a surface of the resonator end face of a laser diode. SOLUTION: On a substrate 1, a plurality of layers 2-9 of 3-nitride semiconductor are formed. An active layer 6 of MQW(multiple quantum well) structure is sandwiched between an n-guide layer 6 and an n-clad layer 4 on one side and a p-guide layer 7 and a p-clad layer 8 on the other side. By removing the other part except for a resonator part by etching, the resonator is formed into a mesa-type. The mesa-type etching of the resonator is so executed that width which is parallel to a substrate surface at the end surface of the resonator is wider than that of the main body part of the resonator, where a current flows vertical to the substrate surface, so that the resonator becomes I-shaped. When the resonator is to be retained by mesa-etching, an edge part of the end surface is etched round, which does not appear at a center part of the end surface.  Thus, the flatness at the end surface where light is reflected is substantially improved.

Inventor: NAKAI HIDEKI
IPC: D06M15/572
Filed: 1987-12-19

CONSTITUTION: A sizing agent comprising an aqueous emulsion obtained by blending (A) an epoxy resin with (B) a water-soluble polyurethane resin having 90-160 deg.C fluidization-starting temperature of a film in the weight ratio of the components A/B regulated so as to be 0.4-1.5, and in the proportion of 0.3-5 wt.% (based on the weight of the fiber) is imparted to a carbon fiber strand such as acrylonitrile-based one, and the resultant carbon fiber strand is dried and heat-treated while pressing the strand to a roller at 90-160 deg.C and bringing the strand into contact with the roller. The obtained carbon fiber strand after sizing treatment is the flat one and excellent in fiber-opening properties.  The stand has further good impregnating ability of a resin and widening properties of the strand at the time of the production of a prepreg, and hardly causes the generation of fuzz and the break of the strand.

Title: Variable driving system for water pump in internal combustion engine
Inventor: SUZUKI SHIGERU
IPC: F02B67/06
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To vary the number of revolutions of an impeller through multiply stages so as to provide an optimum cooling condition by connecting a driving pulley side and a water pump shaft side together by means of a fluid coupling charging electroviscous fluid, and controlling a voltage impressed to a joint electrode. SOLUTION: When cooling water temperature is low, a voltage impressed to electroviscous fluid 32 is lowered or removed on the basis of a signal inputted from a water temperature sensor 39 to an ECU so as to lower viscosity of the fluid 32, and transmission torque from a driving side plate to a driven side plate is lowered, so that the number of revolutions of a pump shaft 6 to a pulley 29 is lowered or the pump shaft 6 is not rotated. When cooling water temperature is increased, the impressed voltage to the fluid 32 is gradually increased so as to increase its viscosity, and the transmission torque is gradually increased, and accordingly, the number of revolutions of an impeller 7 to an engine is changed greatly. Therefore, unnecessary quantity of rotation of the impeller 7 is suppressed through multiple stages according to a temperature change during a cooling time so that a warm-up characteristic is increased, while in a high temperature time, the number of revolutions of the impeller 7 is equalized to engine speed, and a cooling performance is increased.

Title: Light emitting display device
Inventor: MOGI HAJIME
IPC: G09F9/00
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to visually recognize a display without lighting a backlight even in a dimly-lit place. SOLUTION: This light emitting display device is provided with a semi-transparent reflective plate 23 which transmits a part of light transmitted through a liquid crystal display panel 16 transmitting ultraviolet rays and reflects the other part of the light, and a fluorescent layer 24 which emits light reacting with ultraviolet rays contained in the light transmitted through the plate 23.  Therefore, since, in a bright place, most of the light except a part of external light transmitted through the liquid crystal panel 16 is reflected by the plate 23 and made to exit to the side of an observer, information on the liquid crystal panel 16 can visually be recognized, while, in a darkish place, little light is transmitted through the liquid crystal display panel 16 and reflected by the plate 23, but the light is partly transmitted through the plate 23 and made incident on the fluorescent layer 24, and the fluorescent layer 24 reacts with the ultraviolet rays contained in this partial incident light and emits light, therefore, this makes it possible to illuminate the backside of the liquid crystal display panel 16, and visually recognize the information on the liquid crystal display panel 16 even in the darkish place.

Title: Nonlinear distortion compensation circuit and nonlinear distortion compensation power amplifier
Inventor: IWAI HIROSHI
IPC: H03F3/21
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To solve problems of a convertional nonlinear distortion compensation circuit that has had difficulties in realizing a small change in the characteristic because of bias fluctuation and dispersion in components in a highly accurate reverse characteristic in a power amplifier in the case of adopting a simple circuit configuration. SOLUTION: A diode 24 connected in parallel with a main line is connected to ground via a 2nd resistor 25 and a bias is applied from a power terminal 23 to the diode 24 via a 1st resistor 21. When an input level is increased, the diode 24 clips the input waveform and a rectified current flows through the diode 24. Thus, a bias point of the diode 24 is changed to increase an equivalent resistance thereby obtaining a characteristic where the gain is increased with respect to an increase in the input level and the phase is delayed. In this case, the stable characteristic can be realized against bias fluctuation by selecting a sufficiently high resistance for the 1st resistor 21 and the reverse characteristic of the power amplifier can be realized by adjusting the resistance of the 2nd resistor 25.
